ABSTRACT
@#AIM:
To observe the improvement of ocular hemodynamics before and after intraocular pressure(IOP)intervention in patients with non-arteritic anterior ischemic optic neuropathy(NAION).<p>METHODS:
Retrospective case series. Totally 92 patients(92 eyes)with NAION were admitted to the Department of Ophthalmology, Xi'an Fourth Hospital from July 2012 to September 2018. Forty-six patients received only basic treatment without IOP lowering treatment as the conventional treatment group. The other 46 patients were treated with brinzolamide eye drops combined with brimonidine eye drops to lower IOP on the basis of conventional treatment, as the IOP intervention group. Before and after treatment, the blood flow rate of the ophthalmic artery and central retinal artery were measured by color Doppler ultrasound. The IOP, best corrected visual acuity(BCVA), mean visual field defect(MD), retinal nerve fiber layer thickness(RNFLT), ophthalmic artery and central retinal artery peak systolic blood velocity(PSV), end-diastolic blood velocity(EDV), pulse index(PI)and resistance index(RI)were compared.<p>RESULTS:
Before treatment, there were no significant differences in IOP, BCVA(LogMAR), MD, RNFLT, PSV, EDV, PI and RI between the two groups(<i>P</i>>0.05). After 14d of treatment, IOP, BCVA(LogMAR), MD and RNFLT of the two groups were significantly improved compared with those before treatment(<i>P</i><0.05), and the improvement effect of IOP intervention group was better, and the difference between the two groups was statistically significant(<i>P</i><0.05). The PSV, EDV, PI of ophthalmic artery and central retinal artery in the two groups were increased compared with those before treatment, and RI was decreased compared with before treatment; and the changes of PSV, EDV, RI, PI of ophthalmic artery and PSV, EDV, RI of central retinal artery in the IOP intervention group were more significant than those in the conventional treatment group(<i>P</i><0.05). <p>CONCLUSION:
IOP intervention can significantly improve the ocular hemodynamic indexes and improve the visual acuity of patients with NAION.
